Should I trade a pair of tickets to the Phantom of the Opera with a ticket to Perth (yes, bloody again)?

I've always wanted to watch Phantom but I never had the chance to, but I miss Perth so much and I really need to get away for a week or 2. Go on vacation to take my mind off some things and clear my head, have some fun (without parents again. Yay!) . My family friend, Cherie, is willing to house me, and D.'s willing to bring me around (since I can't drive) for a week or so. Though, being able to catch the Broadway cast perform the Phantom of the Opera'd b completely charming! I don't knw.. Help me out?
